Title: Study on the Properties of Styrene-acrylic Emulsion Modified Cement Mortar
Author(s): Shui Zhang, etc.

Abstract:Rapid hardening sulphoaluminate cement,styrene-acrylic emulsion and the proper amount of additives are selected to prepare a new kind of pavement repairing materials aiming at concrete pavement cracks.The modification effects of the styrene-acrylic emulsion on the cement mortar are studied.The results indicate that when the range of polymer/cement ratio(mp/mc) is from 15% to 20%,the 28 days flexural strength increases by 39.00%～48.23%,the 28 days bending bond strength increases by 45.01%～49.60% compared with the blank sample,and the shrinkage rate of the modified mortar is lower.The microstructure and the pore-size distribution of the modified mortar are observed and analyzed by using the scanning electron scope,energy dispersive spectrum and mercury intrusion porosimeter.The modification mechanism of the styrene-acrylic emulsion to the cement mortar is discussed.
